I notice all these controllers are SATA III. When I was struggling to understand why my new 4TB HGST_HDN7240_40ALE_640 SATA III HD ; couldn't seem to deliver a much higher data transfer rate on SATA III than on SATA II.; one comment which was illuminating to me was; " there is no such thing as a SATA III rotating hard-drive" which I took to mean as : ' there is no rotating harddrive; whose heads can transfer data on/off the disk; at anything like 6Gb/s ~ 600GB/s' (SATA III max)'. in contrast to say a SATA III SSD, where this is quite possible ! Apologies if this is merely repeating old news !

Indeed, I was using new cards as a reference point to begin trying to understand what was available. That said, I don't see an abundance of new or used SATA II cards available on places like eBay either.
